Automatic detection device and detection method for circuit board

Abstract

The invention discloses an automatic detection device and detection method for a circuit board and belong to the technical field of circuit board detection. The device comprise a circuit board detection module and a device body; transmission wheels which are horizontally distributed are placed at two ends in the device body; a first crawler belt is connected between the two transmission wheels; the circuit board detection module is installed at the top of the device body above the first crawler belt; clamping bases are evenly welded to the outer surface of the first crawler belt; and two rectangular column-shaped discharging cylinders are symmetrically welded to the top of the device body. A second clamping plate, a positioning plate and a first clamping plate are in contact with the sideedge of the circuit board, the circuit board is clamped through suction cups, damage-free clamping of the circuit board is achieved, deformation and damage of the circuit board are prevented, meanwhile, the circuit board is supported and dragged through L-shaped material receiving bases on second crawler belts on the two sides of a discharging barrel, and under the gravity and falling force of thecircuit board, the other group of L-shaped material receiving bases are displaced, so that the use is convenient.

Description

technical field [0001] The invention relates to the technical field of circuit board inspection, in particular to an automatic detection device and a detection method for a circuit board. Background technique [0002] For the production of printed circuit boards, because many designers do not understand the production process of circuit boards, the circuit diagrams they design are only the most basic circuit diagrams and cannot be directly used for production. Therefore, it is necessary to modify and edit the circuit file before actual production, not only to produce a film diagram suitable for the production process of the factory, but also to produce corresponding punching data, mold opening data, and other data useful for production. It is directly related to the various production projects in the future. [0003] In the existing detection process of circuit boards, a single circuit board is generally tested by placing it inside a fixed mold, and at the same time, the ci...

AI Technical Summary

Problems solved by technology

[0003] In the existing detection process of circuit boards, a single circuit board is generally tested by placing it inside a fixed mold, and at the same time, the circuit board is clamped by a clamp, but in the process of clamping, It is impossible to control the strength of clamping the circuit board, which is easy to damage the corners of the circuit board. At the same time, when the force is too large, it is easy to cause the middle position of the circuit board to warp, which affects the accuracy of detection and is inconvenient to use. Generally, it is not convenient to collect the circuit boards by hand or conveying with the conveyor belt. At the same time, it is easy to cause the circuit boards to be stacked during the circuit board collection process, resulting in damage to the circuit boards.
